Chapter 4: Basic Display Controls
4.1 Introduction
This chapter will help you to become familiar with the functions of the hsb
2
PLUS
Series display unit’s controls in Sonar mode. Information on operating Sonar
display mode is provided in Chapter 5. Instructions for operating the DSM300
with your C Series or E Series display are available in the handbooks for those
products.
Note:
All settings described in this chapter are retained when the unit is powered off.
However, there is a one-minute delay from the time you make the setting change to when
the DSM300 places it in memory. If you power down the sounder less than one minute after
making a change, the setting is lost.
Simulator
The DSM300 includes a simulator function that enables you to practice operating
display controls in Sonar Mode without data from the transducer. Section 2.7
describes how to switch the display to simulator mode.
The DSM300 must be connected to an hsb
2
PLUS Series, C Series or E Series display
unit to show echo sounder data.
4.2 Setting Color and Brightness
Brightness settings depend on the type of display you have. Monochrome
displays offer lighting and contrast settings, while color displays have brightness
and color settings.
Lighting and Contrast (Monochrome Displays)
You can change the level of backlighting and contrast for the screen and keys. The
key lighting is set the same as the screen lighting, except that it remains switched
on at its lowest level even when the screen lighting is turned off, so that you can
always find the keys.
➤
To change the lighting and contrast:
1. Press the
MULTI
key (or the
MULTI
knob on CRT radar units) to display the
soft key controls:
The last-used soft key is highlighted in inverse video (white text on a black
background).
